Pytest 打印到标准输出，尽管输出捕获

Question

I am aware that PyTest captures the output (stdout, stderr, ...) for the tests it executes , and that is an awesome feature I want to keep. However, there is some content that I wish to print to the console immediately from my within conftest.py file, as general information to the person watching the test execution from their terminal. Using a print statement there does not work, as the output of the conftest.py file seems to also be captured, and is only shown if an error happens while executing that file.

Is there a way for me to explicitly bypass this "PyTest output capturing" for a single print statement?

On Unix you could open the controlling terminal and print to it directly:

import os

termfd = open(os.ctermid(), "w")
termfd.write("hello")
termfd.close()
